摘　　要：重载或超载作用是影响沥青混凝土路面车辙的关键因素之一。通过对广东省5条具代表性高速公路的货车轴载调查,得出了该地区不同轴载类型的轴载谱及轮胎接地压强谱。结合调查结果,针对广东沥青混凝土路面车辙病害形式,对重载作用下沥青混凝土面层结构内不同位置、不同深度处的剪应力和压应力进行了理论计算分析,探讨了超载对沥青混凝土路面结构应力分布规律的影响。这为重载交通作用下沥青混凝土路面车辙病害成因分析,以及路面结构和材料设计提供了重要的参考依据。The effect of heavy traffic load or overload is one of leading influencial factors for asphalt concrete pavement rutting.Based on the investigation results of vehicle axle load on five representative highways of Guangdong Province,the tables of axial load and spectrums of tire ground pressure of diferent types of axle loads are obtained.Combined with the survey results,this paper carried out a theoretical calculation of shear stress and compressive stress of different locations and depths of asphalt concrete overlay under heavy traffic loads,especially for the wheel rutting in Guangdong Provience.It also explores the impact of heavy traffic loads on the distribution of structural stress of asphalt concrete pavement,which provides an importance reference for the cause analysis of wheel rutting of asphalt concrete pavemnts under heavy traffic loads and the design of pavement structure and materials.
